DEVELOPING APPARATUS.

Application filed September 5, 1914.

To all whom t may concern.'

.Be it known that I, HARRISON GiNDELE, a, citizen ot the United. States, reslding at Cincinnati, in the county of Hamilton and State.

skilled in the art to which it appertains tomake and use the same.

This invention is a photographic apparatus which is herein termed a developingl negative carrier, and is particularly adapted for the development of sensitized plates, al@ though it is obvious that it can be employed. for the development of films.

One purpose of the invention is to provide a devicel in which photographic plates may be developed by daylight Without the necessity of entering a dark room, the plate being prevented from exposure to light rays.

An aim of the invention is to provide a light proot`-1'eceptacle o1 small dimensions: for a plurality ot sensitized plates or films. which may be immersed in solutions to act upon the emulsion of the plates, and permit of their development, fixation and washing while contined in the receptacle, thereby eliminating handling each individual plate or film, with resultant tendency to injury to the negative, and at the same time relieve the operator of thenecessity of placing his hands in contact with the various solutions as they are applied to the negative subject.

It is well known that those constantly engaged in the development of sensitized photographic negatives or prints are subject to diseases of the cuticle caused by some of the chemicals employed during the developing process. Moreover` in the manner ot developing each plate or film in an open tray within a dark room. the sensitized surface is frequently scratched or injured whle the sensitized emulsion is sott, due to frequent handling of the plates or films during their individual examination and transfer to the various fiuid baths.

The invention embodies a. separable device to permit of proper cleaning and drying of the holder after use, the various elements being arranged in compact form to receive and retain a plurality of exposed subjects in separate compartments protact-,ed `from exposure .to light, andA free Specification of Letters Patent.

trom injury by manual manipulation. The negative carrier is preferably of a size substantially the same, or but a little larger `than a plate holder for a predetermined size plate, and is designed to receive the exposed plate or iilm from the plate holder. A plurallty ot plate developing carriers may be immersed in a single bath, such as that prepared for the time development method, l.transferred to washing vats, thence to fixing baths and thence to washing and dryin receptacles without removing the plates rom the carrier. The various baths and vats may be in an ordinary room and exposed to daylight or artiiicial light, as the exposures are rprotected Vby the carrier `from in- Jury by light. Further objects and advantages oi Vthe invention vwill become apparent from the following detailed description, taken in connection with the accompanying drawings.

One embodiment of the invention is diS-r -closed in the drawings, but it is to be understood that such disclosure is for the purpose of illustration only, and not as defining the limits of the invention.

may be brought in contact with a stream ot water to quickly wash the developed plates, or the carrier may be placed in another receptacle ot ruiming water for the same purpose, after which the carrier with the plates therein may be transferred to another receptacle having a tixed bath. The ordinary steps ot developing, washing and fixing may be carried on with the plates remaining in the developing plate carrier thereby precluding all opportunities :tor injuring the plate, by scratching, abrasion or the like, during the developing process. The

` plates may be removed from the developing carrier after lixation, or may be washed in the same, as may be preferred.

T he various parts ot' the carrier, which are subjected to the chemicals employed in the developing and fixing ot sensitized surfaces, are capable of separation from each other to permit washing and drying of the parts, to etiectually remove all t'ace of chemicals previously employed in connection therewith.

In the embodiment of the invention disclosed in the accompanyingdrawings, the developing negative carrier is shown composed ot tive separable parts, namely, the outer frame which is disclosed in Fig. t, the central body portion which is disclosed in Fig. 2 and is adapted to be slidably mounted in the frame of Fig. 4, the upper section shown in Fig. 1 which is connected to the body section of Fig. 2, and the lower section ot Fig. 3 which is also connected to the body section of Fig. 2. rEhe usual slides ot Fig. 5 are adapted to pass between the frame of Fig. l and the assembled parts of Figs. 1, 2 and 3 when positioned within the frame of Fig. 11.

A practical embodiment of the plate carrier provides the body section ot Fig. 2 with a frame 1 which may be bent from a single piece ot metal to provide wings 1a, the piece of metal being arranged with its edges in juxtaposition as at 2, the front 1b and rear 1c sections bein secured together by a suitable binding plate 3 at the top, which may have rivets et, or any other suitable retaining means, and another binding plate 5 at the bottom thereof, said latter plate 5 being shown provided with an inclined face 5,

which may serve to maintain the plate or film out ot contact with the face 1b or 1c of the body. rlhe lower portion ot the face plates 1b, 1, may be cut away as at G to permit of the entrance o tiuid from a recess :into another plate compartment formed by the plates 1b, l, to permit the fluid to act upon the exposed plate to be inserted therein.

Each of the wings 1a may be provided with suitable openings 8 having an extended portion 9, the metal ot which is cut away and bent inwardly to produce a retaining lug 9a.

The upper section illustrated in Fig. 1 comprises a main plate 10 yvhich may be provided with a plurality of openings 11 which communicate with the plate compartments ot' the holder thereby permitting air and liquid to escape through said openings. Under this plate 10 there may l e provided another plate 12 having a depending tlange shown at 12 on each side of the upper section.

This plate 12 is also bent downwardly at the ends to form wings 12b, and it desired these wings may have inwardly extended flanges 12. As a continuation of the part 12b the plate 12 may be extended to form a locking plate 12d having a slot therein, 15, to be engaged by the lug` 9 of Fig. 2, to et'fectually lock the top section to the body. To release the top section troni the body section pressure may be applied to the plate 12d to press the same inwardly, and release the lug 9 from contact with the slot 15. lf desired this plate 12d may be provided also with an inwardly extended flange lil. There may be secured, also, within the plates l0, 12, a suite able retaining strip, 22, which may be ot wood or any other suitable material, said retaining strip supporting a plurality of battles indicated at which permit liquid and air to escape from the interior of the devclopingl plate carrier, or to admit liquid thereto, and at the same time prevent the admission ol light to the sensitized surfaces contained within the carrier. To this retaining strip 22 there may be secured a resilient slide engaging member 27 operating to 'torce strip oit' tibrous substance. in contact with the ordinary slide 55 (Fig. 5) to exclude light trom the interior oi the carrior. This fibrous substance may be of telt or any other suitable material and may be secured to the retaining strip 22 it desired. The material from which the resilient slide engaging members 2T are termed may also be bent to produce a protecting tlange indicated at 20 between Said members 2T.v

lVhen the upper plate section is secured in its locked position within the body 1, this upper plate section and the body, together with the section illustrated in Fig. 3, may be placed within the trame ot Fig. e, where upon the upper plate section serves to lock all the members Within said frame. This locking means is shown in Fig. 6 as comprising a plurality of angular rods 13, one arm of each rod 13 extending upwardly and protruding above the plate 10 thereof. The rods are maintained in their extended position by suitable means, such as a spring 26, whereby an end of each rod is caused to protrude through an opening in the plate 12b at each side of the upper section. This end of the rod is designed to be seated in a recess 50 formed in the upper portion of the frame of Fig. i to securely lock the parts in position in said frame. 0n this upper plate 1() there shown a substantially similar disk 16 having a central aperture 19 through which is passed the ends 13 of the retaining means, to permit the disk 16 to revolve around said ends. A slotted retaining device 20 is secured to the plate 10 by any suitable means which permits of the rotation of the disk 16, and coperating with this slotted device 20 is a ring-like-member 21 having disconnected ends, said ends of the ringlike-.member 21 being positioned within the slot of member 20 and in Contact with the ends 13a of the resilient retaining device 13, whereby upon compression of the lower portion of said ring-like-member 21, the ends thereof will engage the endslSu of the retaining device and retract the other ends of said devices 13 from engagement with the recess 50 and permit' of the removal of the interior portion of the plate carrier from its frame.

The lower section of the plate developing carrier, which is illustrated in Fig. 3, is shown provided with a base plate 31 which may have upstanding flai'iges 32 around the sides thereof. The ends of this base plate 31 is practically extended to form a retaining plate 32 which may be provided with side flanges if desired, and which is shown as lmving a slot 15, similar to the slot of Fig. 1. The retaining plate 32 is breferably made of resilient material and is designed to be secured within the channeled wings 1a of the body member 1, to have the retaining lu g 9 engage the slot 15 and lock this base plate to the vinner member 1 prior to the insertion of parts 1, 2 'and within the part of F ig. l. The base plate 31 is provided with an aperture 39, to permit of the ingress of any suitable fiuid therethrough whereby it may have access to the contents of the carrier. To prevent light from gaining access to the contents of the carrier. there may be provided a suitable housing having the part 3-1 which serves as means to inclose a baffle member of any preferred construction. In the drawings, the baflie is shown as a plate having a plurality of zig-zag portions, 43, each of the portions being cut away as at 43 on opposite walls thereof to permit the fiuid to pass from one baiiie tothe next in a tortuous path, and at the same time to prevent the admission of light from the contents of the receptacle to said baffle. The endV walls kof the member 34 may be cut away as at 37 to permitl the fluid to escape from the battle device and in Contact with the ends 32 in its path to the interior of the recess and through the aperture 6. 1f desired the baffle device may be provided with a cover 36 to inclose the same, said cover being cut away at the ends to register with the cut out portion 37.

The frame of Fig. t is shown provided with the side members dit having inturned flanges 45 around all four sides thereof. The base portion 46 provided with an aperture 47 which preferably registers with the aperture 39 in the base of the bottom section of Fig. 3. The side walls 4A may be provided with a retaining lug 54e, the purpose of which will be understood, as hereinafter set forth. The upper portion L18 of the frame is made of one piece of metal, and is provided with the usual shoulder which is common to plat-e holders, the said shoulder being employed to retain the developing platel carrier in position upon the trans- 't'er device and it is obvious that this shoulder may be omitted if found desirable or any suitable equivalent employed therefor. The plate 18 may be beveled inwardly as at 52 to insure the guiding of the plate slide 55 of Fig. 5, and the upper inner portion of this member 118 may be turned over as at +19 to securely bind a strip of light excluding material 51. If desired the end plates may be cut away at the top, as at 51a to provide a seat for the ends of plate 10 of the upper section.

The usual slides, illustrated in Fig. 5 may be provided with an inturned portion 57, and an extended finger portion having a slot 56 therein. lWhen the Slide is inserted to its fullest extent, the flange 57 will engage the upper edge of the member of the blate 10. whereupon the disl-like-member 16 can berotated until a flattened surface 17 thereof is out of register with the slot 56 and an arcuated portion of said disk will pass through said slot 56 and serve to etfectually lock the plate holders in their :inserted position. It found desirable this disk 16 may have but one or tvo of such flattened portions wherebv a partial. rotation of the dish will serve to unlock or loch but one plate slide at a. time.

It will be obvious that when the plate developing carrier is loaded with undeveloped plates, the entire structure may be deposited in any ordinary receptacle containing develoninn. washing. or'fixing fluid, and that the tiuid will pass through the openings 47 or 11 therein and into contact with the chambers which confine the sensitized surfaces.
